One Direction's Louis Tomlinson calls Thursday's honor "the icing on the
cake."

MTV's team of music staffers chose Carly Rae Jepsen's "Call Me Maybe" as
song as the year.

One Direction placed third on the U.K. version of "The X Factor" in 2010 and
made their U.S. debut in March with the No. 1 album "Up All Night." Their
sophomore album, "Take Me Home," was the year's third-highest debut.
